IMPROVEMENT IN MACHINES FOR CRlMPlNG BOOT AND SHOE COUNTERS-Specitication forming part of Letters Patent N0.147,5S7, dated Februa y17, 1874; application. filed January 3, 1873. I

To all whom it may concern:

Be it known that I, EMERY ANDRnws, of \Velchville, in the county ofOxford, Maine, have invented an Improved Machine for Crimping Countersfor Boots and Shoes, of which the following is a specification Mypresent invention relates to a peculiar machine or apparatus forcrimping or shaping counters or heelstiffeners for boots and shoes. Theinvention consists in the combination of a forming and propellingplunger, pressurejaws, and a crimping mouth-piece having a flaringlance-shaped notch, with or without a finishing-roller, also, inmechanism for reciprocating the plunger in a peculiar manner, ashereinafter set forth.

Figure l is a partially-sectionized side ele vation of mycounter-crimping machine. Fig. 2 is a front elevation of the same. Figs.3 and 4 are side and rear elevations of my drivingpulley and clutch.Fig. 5 is a front elevation, from which a portion of the housing isbroken away, representing the crimping apparatus proper on alargerscale. Fig. 6 is ahorizontal section at the line 00 m. a

A is a stand or frame, having in front of it vertical guides B, for aformer or plunger, G, having a rounded lower end to correspond with theinner or concave surface of the desired counter. D D are jaws, havingshanks E, which occupy horizontal guides F. These jaws have roundedinner edges (1 to enable the easy insertion of the counter-blank betweenthem, and their width from front to back is equal to the desired heightof the crimped counter. G are springs, which operate to press the jaws DD toward each other, so as, when a blank has been forced downwardbetween the jaws, to press the blank tightly around the plunger. When inoperation the jaws D D work horizontally from and toward each otherbetween the face A of the frame,

and a mouth-piece, 11, having the represented lance-shaped notch I,whose edges are chamfered underneath, as shown by strong lines in Fig.1, and by dotted lines in Fig. 5. The of fice of the mouth-piece H is tobend overto a position at right angles to the main body of the straightedge of the blank, so as to form a welt or flange, 5, for stitching orpegging to the sole. The said. flange, when bent perma- The plunger 0may be reciprocated by any desired means. I will describe those employedby me. The middle portion of the plunger is expanded laterally, so as toassume the form of a disk, M, whose disk side has a horizontal groove,m, which receives a wrist, N, from a crank or disk, 0, on the end of ashaft, P, journaled horizontally in the frame. This shaft carries aslidable clutch, Q, whose rotation with said shaft is compelled by afeather, p, which occupies a seat, q, in the clutch. \Vhen this clutchis slid forward, its pin It enters a hole, 8, in a driving-pulley, S,which, except when so engaged, revolves freely upon the shaft 1?. 0n therear side of this pulley is a cam, T. The clutch Q has a circumferentialgroove, U, which receives the points o of a yoke, V, which is fulcrumedat o in the frame. Said yoke has on its front side a guidebox, \V, for abolt, X, which is held by spring Yin contact with rear surface of pulleyS, and remains non-effective until the rotation of the pulley bringsthecam Tin contact with said bolt, so as to throw the head of yoke back,and thus disengage the pin R from the hole sin the pulley, and bring thelatter to rest, which action, occurring at the extreme elevation of theplunger 0, affords time for the attendant to place another blank uponthe tops of the jaws D D. A cord or chain, Z, depending fronrthe bolt X,is attached to a treadle, (not sl'1own;) and when the attendant desiresthe plunger to descend, he has only to depress the treadle with hisfoot, so as to draw the bolt X away from the pulley, and permit the pinR to.

re-enter the pulley, and cause the rotation of the shaft, and,consequently, the descent of the plunger, which, having bent, orimped,and discharged the counter, reascends and comes automatically to rest,and so remains until again started by the attendant, who, it will beseen, has thus complete control of the movements, said movements being,however, wholly due to the motive power, and imposing no labor on theperson operating the machine other than the manipulation of the blanksand depression ofthe treadle, as before stated.

I first prepare a sufficient number of blanks. These may consist ofsemi-elliptical sheets, whose minor radius equals the desired height,and whose major diameter equals the desired circuit of the counter. Theblanks may be cut from the leather-board or other material, in anypreferred manner. The pulley S being now rotated by belt connection withany prime mover, a blank is placed on top of the jaws D D with itsstraight edge outward. The bolt X being now withdrawn, this action atoncejenables the clutch Q to engage with the pulley, and thus rotate theshaft P, and depress the plunger 0, which plunger, depressing the blankbetween the jaws D D, bends the said blank around the plunger, and atthe same time forces that portion of the straight edge of the blankwhich projects above the face of the jaws under the chamfered or flaringmouth-piece, whose lance formed edges operate to gradually crowd overthe consecutive portions'of said edge, beginning with those portionsfarthest from the middle of the blank, so as to lap the samesuccessively and regularly over one another much more effectually thanwould occur were the notch in said mouth-piece of a semicircular form.The flat portion of the mouthpiece sinoothes the crimped edge, and thefinishing-roller compresses and sets the same.

I claim as new and of my invention 1. The described arrangement ofreciprocat in g plunger 0, pressure-jaws D D, and the flarin g andlance-notched mouth-piece H, substantially as and for the purpose setforth.

2. In combination with the plunger 0, press -ure-jaws D D, and themouth-piece H, the finplunger G, in the manner and for the purposespecified.
